Lesser

A serverless, cost-optimized ActivityPub implementation built with Go, AWS Lambda, and the Lift framework.

Overview

Lesser is a Mastodon-compatible federated social media platform that runs entirely on AWS serverless infrastructure. It provides full ActivityPub federation while maintaining costs at a fraction of traditional server-based implementations.

Key Features

  • Full ActivityPub Support: Complete federation with Mastodon and other ActivityPub servers
  • Serverless Architecture: Dozens of Lambda functions for API + background processing
  • Cost Optimization: Built-in cost tracking and budget controls for sustainable operation
  • Multi-Tenant Support: Run multiple instances from a single deployment
  • GraphQL API: Modern API with 60+ operations alongside Mastodon REST compatibility
  • WebSocket Streaming: Real-time updates for timelines and notifications
  • AI Integration: Optional semantic search and content moderation via AWS Bedrock
  • Enterprise Monitoring: CloudWatch dashboards, EMF metrics, and comprehensive alerting

Architecture

Lesser uses AWS CDK with the Lift framework for infrastructure:

  • Lambda Functions: Event-driven compute for all operations
  • DynamoDB: Single-table design with 8 GSIs for efficient queries
  • S3 + CloudFront: Global CDN for media delivery
  • API Gateway: HTTP API with custom domain support
  • SQS: Reliable message queuing for federation and async processing
  • EventBridge: Scheduled tasks for aggregation and maintenance

Quick Start

Prerequisites
  • AWS credentials configured (for example: aws sso login --profile ... or aws configure)
  • AWS CDK v2 installed (npm install -g aws-cdk)
  • Go 1.25 or later
  • A public Route53 hosted zone that exactly matches your base domain (for example: example.com)
Basic Deployment
# Build the operator CLI
go build -o lesser ./cmd/lesser

# Deploy dev + live (and optionally staging)
./lesser up \
  --app my-lesser \
  --base-domain example.com \
  --aws-profile Penny \
  --out ~/.lesser/my-lesser/example.com/bootstrap.json

Notes:

  • The live stage uses the apex domain (example.com), while dev uses dev.example.com (and staging uses staging.example.com if enabled).
  • On first deploy, --out <path> is required so you don’t lose the 24-word Ethereum mnemonic (the file is created with 0600 permissions).
  • A local deployment receipt is written to ~/.lesser/<app>/<base-domain>/state.json.

Configuration

Infrastructure defaults (memory/timeouts, tables/buckets, CloudFront, etc.) live in infra/cdk/stacks/ and infra/cdk/inventory/.

Environment Variables

Runtime configuration is managed in AWS for deployed stacks; see docs/configuration.md for the canonical reference.

Key configuration options:

INSTANCE_TITLE="My Lesser Instance"
INSTANCE_ADMIN_EMAIL="admin@yourdomain.com"
FEDERATION_ENABLED=true
REGISTRATIONS_OPEN=false
MAX_STATUS_CHARS=5000

Cost Management

Lesser includes comprehensive cost tracking:

  • Real-time cost calculation for every operation
  • Per-instance budgets with automatic enforcement
  • Cost aggregation via scheduled Lambda functions
  • Budget alerts through SNS and CloudWatch

Typical monthly costs:

  • Development: < $5
  • Small instance (100 users): $10-20
  • Medium instance (1000 users): $50-100
  • Large instance (10000 users): $200-500

Monitoring

Built-in observability features:

  • CloudWatch Dashboards: Comprehensive metrics for all components
  • EMF Metrics: Structured metrics with dimensions
  • X-Ray Tracing: Distributed tracing for debugging
  • Custom Alarms: Automatic alerting for errors and performance issues

Access your dashboard at:

./lesser dashboard --app <app> --env live --region us-east-1

API Documentation

Lesser provides three API interfaces:

REST API (Mastodon-compatible)
  • Full Mastodon v1 API compatibility
  • Additional Lesser-specific endpoints
  • OAuth 2.0 authentication
GraphQL API
  • 60+ operations for queries, mutations, and subscriptions
  • DataLoader for N+1 query prevention
  • Real-time subscriptions via WebSocket
  • Published schema: The canonical schema we ship to clients lives at docs/contracts/graphql-schema.graphql. It is generated from the modular source files (graph/core.graphql, graph/phase1.graphql, graph/phase2.graphql, graph/phase3.graphql) by running ./lesser schema (or ./scripts/generate_schema.sh). Always rerun it before sharing or checking in schema changes so frontend teams see every type in one place.
WebSocket Streaming
  • Real-time timeline updates
  • Notification streaming
  • Presence and typing indicators

Development
